HI Neil, first I dont know if you can do it. As a basic rule if not same version, Master version should always be older than slave, but I am afraid binary log format is too different from 3.23 to 5.1
If you have problems with direct replication In your case I would suggest a couple of solutions. - upgrade 3.23 to 4.1 and then setup replication from 4.1 to 5.14) - setup a chain replication with intermediate versions like: 3.23-->4.1-->5.1 Just a couple of ideas. You should not have big problems in upgrading 3-->4, if you want some idea on how to do it let me know.
